- Abstract
INTRODUCTION : Le liposarcome est une tumeur mésenchymateuse primitive rare, développée aux dépends des tissus adipeux. Il est constitué de quatre sous-types histologiques notamment les sous- types bien différenciés, myxoïde, pléomorphe et dédifférencié. La localisation préférentielle est la cuisse. Nous rapportons une observation d’un liposarcome myxoïde à cellule ronde à localisation fessière. OBSERVATION : Un homme âgé de 56 ans, vendeur de légumes, originaire de la Guinée Conakry, présentait depuis deux ans une tumeur de la fesse droite. L’examen retrouvait une tumeur inflammatoire, ulcérée du quadrant supéro-externe de la fesse droite bien limitée, à fond purulent jaunâtre avec quelques plages de nécrose, mesurant environ huit cm. Des adénopathies inguinales bilatérales étaient retrouvées. Les hypothèses diagnostiques étaient les suivantes : carcinome épidermoïde, lymphome cutané, métastases cutanées. L’examen anatomopathologique mettait en évidence une prolifération tumorale maligne occupant toute la hauteur du derme et faite de lipoblastes, de flasques mucineux bleuâtres disposées en vastes zones et des plages d’adipocytes très pléomorphes avec des noyaux irréguliers à disposition interstitielle diffuse. Le diagnostic de liposarcome myxoïde à cellules rondes avait été retenu. La tomodensitométrie thoraco-abdomino-pelvienne, réalisée dans le cadre du bilan l’extension, avais mis en évidence un aspect compatible avec des localisations néoplasiques secondaires pleuropulmonaires, hépatiques, cutanées et ganglionnaires. L’extension ganglionnaire concernaient les aires inguinales et iliaques internes et externes bilatérales avec des adénopathies de tailles variables dont la cible inguinale droite mesure 96x94 mm. Ces adénopathies étaient compressives compliquées d’une urétro-hydronéphrose de stade II à droite et d’une thrombose veineuse cave partielle. Le patient a été traité par chimiothérapie (adriamycine – carboplatine). L’évolution était rapidement fatale au bout de quelques semaines après la première cure de chimiothérapie. Les liposarcomes sont des tumeurs malignes rares représentant moins de 1% des tumeurs malignes. Quatre sous-types histopathologiques sont identifiés par l’OMS. Notre observation est caractéristique par sa topographie et l’évolution rapidement fatale avec des métastases multiples. Le sous-type myxoïde est le plus fréquent représentant 25% des liposarcomes et 5% des sarcomes des tissus mous atteignant généralement les adultes jeunes avec un pic d’incidence entre 40 et 60 ans. CONCLUSION : Il faudrait évoquer un liposarcome devant toute tumeur des parties molles localisée à la région fessière. L’examen anatomopathologique est incontournable pour confirmer le diagnostic et préciser le sous-type histopathologique.

Age and growth of Rhizoprionodon acutus were estimated from vertebrae age bands. From December 2009 to November 2010, 423 R. acutus between 37 and 112 cm total length (LT ) were sampled along the Senegalese coast. Marginal increment ratio was used to check annual band deposition. Three growth models were adjusted to the length at age and compared using Akaike's information criterion. The Gompertz growth model with estimated size at birth appeared to be the best and resulted in growth parameters of L∞ = 139.55 (LT ) and K = 0.17 year(-1) for females and L∞ = 126.52 (LT ) and K = 0.18 year(-1) for males. The largest female and male examined were 8 and 9 years old, but the majority was between 1 and 3 years old. Ages at maturity estimated were 5.8 and 4.8 years for females and males, respectively. These results suggest that R. acutus is a slow-growing species, which render the species particularly vulnerable to heavy fishery exploitation. The growth parameters estimated in this study are crucial for stock assessments and for demographic analyses to evaluate the sustainability of commercial harvests.

Summary A Human Immunodeficiency Virus (HIV) investigation on blood donors was carried out in the Dakar «Hopital Principal from 1987 to 1993. The results of this investigation on 42,724 donors are given in this article. The prevalence rate among this population reaches 2.1 per thousand. After decreasing from 5.7 per thousand to 0.7 per thousand in 1990, the prevalence rate increased again and reached 2.2 per thousand in 1993. The prevalence rate of seropositive female donors (5.4 per thousand) was 3 times higher than that of seropositive male donors (1.8 per thousand). A better detection of potentially dangerous donors seems to be one of the authors' challenges.

- Abstract
Background: Physiologic and immunologic adaptations in pregnancy may increase the risk of adverse outcomes from respiratory viral infections. However, data are limited on longer-term outcomes after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy prior to widespread vaccine availability., Methods: Using electronic health record data, we retrospectively compared 6-, 12-, and 18-month outcomes including death and rehospitalization between pregnant and nonpregnant reproductive-aged individuals hospitalized for SARS-CoV-2 infection between 2020 and 2021 at 2 academic referral hospitals., Results: There were 190 nonpregnant and 70 pregnant participants. Mean age was 31 years for pregnant and 34 years for nonpregnant participants. For pregnant patients, mean gestational age at coronavirus disease 2019 (COVID-19) diagnosis was 36 weeks, 54% delivered by cesarean, and 97% delivered a live birth. Compared to pregnant participants, nonpregnant participants had a higher prevalence of baseline comorbidities and a higher proportion received mechanical ventilation (84% vs 55%). Index hospitalization complications (31% vs 17%) and mortality (3% vs 0%) were more common in nonpregnant participants. Over 18 months following index hospitalization, 39 (21%) nonpregnant and 5 (7%) pregnant participants were readmitted, most for infection (28/44 [64%]). Most readmissions occurred within 6 months. There were no posthospitalization deaths in the pregnant group., Conclusions: Pregnant people with severe COVID-19 disease had a low rate of severe adverse outcomes after index hospitalization. The low readmission rate is reassuring that pregnant individuals may not be at higher risk for long-term severe adverse health outcomes after COVID-19 compared to the nonpregnant reproductive-aged population, possibly because any increased risk conferred by pregnancy resolves soon after delivery., Competing Interests: Potential conflicts of interest. K. J. G. reports consultation for BillionToOne, Aetion, Roche, and Janssen Global, outside the scope of the submitted work. All other authors report no potential conflicts., (© The Author(s) 2024.

- Abstract
Objective: The purpose of this study is to understand experiences of respectful maternity care (RMC) from the perspective of birthing people in the United States from 2013 to 2018., Methods: We conducted an online cross-sectional survey of United States birthing people ages 18-50 in April 2018 using SurveyMonkey Audience. Quantitative survey data consisted of demographics and responses to RMC indicators. Qualitative data consisted of comments from individuals regarding their birth experiences., Results: 1036 birthing people participated in the survey. Most births (95%) occurred in hospitals. 16.3% of Black or African American participants reported discrimination compared to 5.5% of participants who did not identify as Black or African American (p < 0.001). Participants who speak a language other than English were also more likely to report discrimination. 19.5% of all respondents felt neglected during their birth experience. Most prevalent experiences of disrespect and mistreatment were related to neglect (most commonly in postpartum phase of care), poor interpersonal communication, lack of respect for patient wishes, negative experience with breastfeeding services, peripartum complications, and discrimination., Conclusion for Practice: Birthing people in the United States experience many forms of mistreatment, particularly those who identify as Black or African American or speak a language other than English. Patients described experiencing neglect most commonly after birth-an opportunity to improve the provision of RMC postpartum. Strategies to improve quality of maternal health care in the United States should include the provision of RMC as part of a larger effort to reduce inequities in maternal health experiences and outcomes., (© 2024.

- Abstract
We conducted a retrospective cohort study of pregnant patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection by RNA polymerase chain reaction test or home test who were counseled about taking nirmatrelvir-ritonavir if they were within 5 days of symptom onset. Obstetric and coronavirus disease 2019 (COVID-19) outcomes were compared between patients who did and did not take the medication. Overall, 114 individuals took nirmatrelvir-ritonavir and 323 did not. The cohorts were comparable, including high rates of vaccination in both groups. Nirmatrelvir-ritonavir was well-tolerated, with no patients discontinuing medication due to side effects. There were no intensive care unit admissions in either group. Most obstetric and medical outcomes were similar between those taking and not taking nirmatrelvir-ritonavir. Patients taking nirmatrelvir-ritonavir had significantly higher rates of surgical site infection (3 [2.7%] vs 0 [0%], P =.02) and preeclampsia (11 [9.6%] vs 12 [3.7%], P =.02). Outcome event numbers were too small for multivariable modeling. These preliminary data may be reassuring to clinicians and patients who would like to use nirmatrelvir-ritonavir in pregnancy., Competing Interests: Financial Disclosure The authors did not report any potential conflicts of interest., (Copyright © 2023 The Author(s).

- Abstract
Objective: The nine-valent human papillomavirus (9vHPV) vaccine is highly effective at preventing cervical cancer, yet U.S. vaccination rates remain low. The objective of this study was to evaluate integration of 9vHPV inpatient vaccination into routine postpartum care., Methods: Obstetrics professionals at an academic urban referral center received an emailed protocol outlining a novel 9vHPV vaccination program of postpartum inpatients aged 26 years or younger. A retrospective evaluation from March 2021 to March 2022 was conducted to evaluate implementation. Characteristics of patients vaccinated before pregnancy compared with vaccine-eligible patients (none, unknown, or partially vaccinated status) were compared by the use of χ2, analysis of variance, and multivariable logistic regression. Similarly, analyses were performed comparing vaccine-eligible patients who did with those who did not receive an inpatient 9vHPV vaccination., Results: Of 569 postpartum inpatients, 370 (65.0%) were already vaccinated, 70 (34.2%) were never vaccinated, 49 (24.6%) were partially vaccinated, and 80 (14.1%) had unknown status. Of vaccine-eligible patients, 46 (23.1%) received 9vHPV vaccination as an inpatient. In multivariable analysis, race and ethnicity, marital status, and primary language were significant predictors of vaccination before pregnancy. Among vaccine-eligible patients, inpatient vaccination recipients were primarily Hispanic, Spanish speaking, and publicly insured. In multivariable analysis of vaccine-eligible patients, receiving care from the certified nurse midwifery practice was the only independent predictor of vaccination (odds ratio 2.4, 95% CI 1.02-5.74, P=.04)., Conclusion: Non-Hispanic White, Spanish-speaking, and married patients were disproportionally undervaccinated in our baseline population, but about one quarter of vaccine-eligible patients received 9vHPV vaccination postpartum. Inpatient postpartum 9vHPV vaccination may help narrow disparities in vaccination., Competing Interests: Financial Disclosure Stephanie Alimena reports receiving payment from Roche Diagnostics. Sarah Feldman disclosed that money was paid to her institution from NCI and the Society to Improve Diagnosis in Medicine. She received payment from UpToDate and the University of New Mexico.

- Abstract
As intrapartum fevers are not always infectious in origin, determining whether antibiotics are indicated is challenging. We previously sought to create a point-of-care calculator using clinical data available at the time of an intrapartum fever to identify the subset of women who require antibiotic treatment to avoid maternal and neonatal morbidity. Despite the use of a comprehensive dataset from our institutions, we were unable to propose a valid and highly predictive model. In this commentary, we discuss why our model failed, as well as future research directions to identify and treat true intraamniotic infection. Developing a risk-stratification model is paramount to minimizing maternal and neonatal exposure to unnecessary antibiotics while allowing for early identification of women and babies at risk for infectious morbidity. KEY POINTS: · Determining whether antibiotics are indicated in intrapartum fever is challenging.. · Developing a risk-stratification model for febrile laboring women is critical to decreasing harm.. · A point-of-care calculator based on clinical and biomarker data is the necessary approach.., Competing Interests: None declared., (Thieme.

- Abstract
Few obstetrician-gynecologists (ob-gyns) provide abortion care, resulting in abortion being separated from other reproductive health care. This segregation of services disrupts the ob-gyn patient-clinician relationship, generates needless costs, delays access to abortion care, and contributes to stigma. General ob-gyns have both the skills and the knowledge to incorporate abortion into their clinical practices. In this way, they can actively contribute to the protection of abortion access now with the loss of federal protection for abortion under Roe v Wade . For those who live where abortion remains legal, now is the time to start providing abortions and enhancing your abortion-referral process. For all, regardless of state legislation, ob-gyns must be leaders in advocacy by facilitating abortion care-across state lines, using telehealth, or with self-managed abortion-and avoiding any contribution to the criminalization of those who seek or obtain essential abortion care. Our patients deserve a specialty-wide concerted effort to deliver comprehensive reproductive health care to the fullest extent., Competing Interests: Financial Disclosure Deborah Bartz receives royalties from UpToDate related to medication abortion. She also indicated that, although the article describes the U.S. Food and Drug Administration–approved regimen for medication abortion with mifepristone and misoprostol, it also includes text on self-sourcing these prescription medications. The other authors did not report any potential conflicts of interest., (Copyright © 2022 The Author(s). Published by Wolters Kluwer Health, Inc.)

- Abstract
Objective: This study aimed to characterize attitudes toward novel coronavirus disease 2019 (COVID-19) vaccination and to evaluate factors associated with vaccine uptake among pregnant individuals., Study Design: An anonymous survey was distributed to a convenience sample of pregnant individuals receiving prenatal care at two large urban academic hospitals in a single health care network in Massachusetts. Individual demographic variables were included in the survey along with questions assessing attitudes toward COVID-19 and vaccination in pregnancy. Data were analyzed using parametric or nonparametric tests when appropriate, and associated odds ratios (OR) were calculated via univariable logistic regression., Results: There were 684 surveys distributed, and 477 pregnant and postpartum individuals completed the survey, for a response rate of 69.7%. Overall, 233 (49.3%) had received or were scheduled to receive a COVID-19 vaccine. Age, White race, non-Hispanic or Latinx ethnicity, working from home, and typical receipt of the influenza vaccine were associated with COVID-19 vaccination. Further, 276 respondents (58.4%) reported that their provider recommended the COVID-19 vaccine in pregnancy; these participants were more likely to have received a vaccine (OR = 5.82, 95% confidence interval [CI]: 3.68-9.26, p < 0.005). Vaccinated individuals were less likely to be worried about the effects of the vaccine on themselves (OR = 0.18, 95% CI: 0.12-0.27, p < 0.005) or their developing babies (OR = 0.17, 95% CI: 0.11-0.26, p < 0.005). Unvaccinated individuals were less likely to report that it is easy to schedule a COVID-19 vaccine (OR = 0.56, 95% CI: 0.34-0.93, p = 0.02), to travel to receive a vaccine (OR = 0.19, 95% CI: 0.10-0.36, p < 0.005), and to miss work to receive a vaccine (OR = 0.30, 95% CI: 0.18-0.48, p < 0.005)., Conclusion: Strategies are needed to improve patient education regarding vaccine side effects and safety in pregnancy. Policy changes should focus on making it feasible for patients to schedule a vaccine and miss work without loss of pay to get vaccinated., Key Points: · There were racial and ethnic disparities in COVID-19 vaccination.. · Unvaccinated respondents were more likely to be concerned about vaccine effects for themselves or their growing babies.. · Unvaccinated respondents cited work and scheduling-related barriers to vaccination, indicating areas for advocacy.., Competing Interests: None declared., (Thieme.

- Abstract
Background: Pregnant and lactating women were excluded from initial coronavirus disease 2019 vaccine trials; thus, data to guide vaccine decision making are lacking., Objective: This study aimed to evaluate the immunogenicity and reactogenicity of coronavirus disease 2019 messenger RNA vaccination in pregnant and lactating women compared with: (1) nonpregnant controls and (2) natural coronavirus disease 2019 infection in pregnancy., Study Design: A total of 131 reproductive-age vaccine recipients (84 pregnant, 31 lactating, and 16 nonpregnant women) were enrolled in a prospective cohort study at 2 academic medical centers. Titers of severe acute respiratory syndrome coronavirus 2 spike and receptor-binding domain immunoglobulin G, immunoglobulin A, and immunoglobulin M were quantified in participant sera (n=131) and breastmilk (n=31) at baseline, at the second vaccine dose, at 2 to 6 weeks after the second vaccine, and at delivery by Luminex. Umbilical cord sera (n=10) titers were assessed at delivery. Titers were compared with those of pregnant women 4 to 12 weeks from the natural infection (n=37) by enzyme-linked immunosorbent assay. A pseudovirus neutralization assay was used to quantify neutralizing antibody titers for the subset of women who delivered during the study period. Postvaccination symptoms were assessed via questionnaire. Kruskal-Wallis tests and a mixed-effects model, with correction for multiple comparisons, were used to assess differences among groups., Results: Vaccine-induced antibody titers were equivalent in pregnant and lactating compared with nonpregnant women (pregnant, median, 5.59; interquartile range, 4.68-5.89; lactating, median, 5.74; interquartile range, 5.06-6.22; nonpregnant, median, 5.62; interquartile range, 4.77-5.98, P=.24). All titers were significantly higher than those induced by severe acute respiratory syndrome coronavirus 2 infection during pregnancy (P<.0001). Vaccine-generated antibodies were present in all umbilical cord blood and breastmilk samples. Neutralizing antibody titers were lower in umbilical cord than maternal sera, although this finding did not achieve statistical significance (maternal sera, median, 104.7; interquartile range, 61.2-188.2; cord sera, median, 52.3; interquartile range, 11.7-69.6; P=.05). The second vaccine dose (boost dose) increased severe acute respiratory syndrome coronavirus 2-specific immunoglobulin G, but not immunoglobulin A, in maternal blood and breastmilk. No differences were noted in reactogenicity across the groups., Conclusion: Coronavirus disease 2019 messenger RNA vaccines generated robust humoral immunity in pregnant and lactating women, with immunogenicity and reactogenicity similar to that observed in nonpregnant women. Vaccine-induced immune responses were statistically significantly greater than the response to natural infection. Immune transfer to neonates occurred via placenta and breastmilk., (Copyright © 2021 The Author(s). Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Pregnant and lactating women were excluded from initial COVID-19 vaccine trials; thus, data to guide vaccine decision-making are lacking. We sought to evaluate the immunogenicity and reactogenicity of COVID-19 mRNA vaccination in pregnant and lactating women., Methods: 131 reproductive-age vaccine recipients (84 pregnant, 31 lactating, and 16 non-pregnant) were enrolled in a prospective cohort study at two academic medical centers. Titers of SARS-CoV-2 Spike and RBD IgG, IgA and IgM were quantified in participant sera (N=131), umbilical cord sera (N=10), and breastmilk (N=31) at baseline, 2nd vaccine dose, 2-6 weeks post 2nd vaccine, and delivery by Luminex, and confirmed by ELISA. Titers were compared to pregnant women 4-12 weeks from native infection (N=37). Post-vaccination symptoms were assessed. Kruskal-Wallis tests and a mixed effects model, with correction for multiple comparisons, were used to assess differences between groups., Results: Vaccine-induced immune responses were equivalent in pregnant and lactating vs non-pregnant women. All titers were higher than those induced by SARS-CoV-2 infection during pregnancy. Vaccine-generated antibodies were present in all umbilical cord blood and breastmilk samples. SARS-CoV-2 specific IgG, but not IgA, increased in maternal blood and breastmilk with vaccine boost. No differences were noted in reactogenicity across the groups., Conclusions: COVID-19 mRNA vaccines generated robust humoral immunity in pregnant and lactating women, with immunogenicity and reactogenicity similar to that observed in non-pregnant women. Vaccine-induced immune responses were significantly greater than the response to natural infection. Immune transfer to neonates occurred via placental and breastmilk.

- Abstract
Improving quality of care in low-and middle-income countries (LMICs) is a global priority, specifically around maternal and newborn care, where mortality and morbidity remain unacceptably high. Cesarean delivery is the most common procedure in women, thus evaluating quality around the provision of this intervention provides insight into overall quality of care around childbirth. In this review we provide an overview on the quality of care around cesarean delivery using the six domains of quality proposed by the Institute of Medicine: equity, effectiveness, efficiency, safety, timeliness and patient-centered care. We review evidence of potential quality gaps in each of these domains around cesarean delivery in LMICs, discuss opportunities for improvement and provide suggestions on metrics for tracking quality in each of these domains. As cesarean delivery rates increase globally, efforts to ensure quality will be essential to drive continued and sustained improvements in global maternal and newborn outcomes., (© 2021 Elsevier Ltd.

- Abstract
Background: While studies from large cities affected by coronavirus disease 2019 (COVID-19) have reported on the prevalence of SARS-CoV-2 in the context of universal testing during admission for delivery, the patient demographic, social and clinical factors associated with SARS-CoV-2 infection in pregnant women are not fully understood., Objective: To evaluate the epidemiological factors associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in women admitted for labour and delivery, in the context of universal screening at four Boston-area hospitals., Methods: In this prospective cohort study, we reviewed the health records of all women admitted for labour and delivery at four hospitals from the largest health system in Massachusetts between 19 April 2020 and 27 June 2020. We calculated the risk of SARS-CoV-2 infection, including asymptomatic infection. We calculated associations between SARS-CoV-2 infection and demographic and clinical characteristics., Results: A total of 93 patients (3.2%, 95% confidence interval 2.5, 3.8) tested positive for SARS-CoV-2 infection on admission for labour and delivery out of 2945 patients included in the analysis; 80 (86.0%) of the patients who tested positive were asymptomatic at the time of testing. Factors associated with SARS-CoV-2 infection included the following: younger age, obesity, African American or Hispanic race/ethnicity, residence in heavily affected communities (as measured in cases reported per capita), presence of a household member with known SARS-CoV-2 infection, non-health care essential worker occupation and MassHealth or Medicaid insurance compared to commercial insurance. 93.8% of patients testing positive for SARS-CoV-2 on admission had one or more identifiable factors associated with disease acquisition., Conclusions: In this large sample of deliveries during the height of the surge in infections during the spring of 2020, SARS-CoV-2 infection was largely concentrated in patients with distinct demographic characteristics, those largely from disadvantaged communities. Racial disparities seen in pregnancy persist with respect to SARS-CoV-2 infection., (© 2020 John Wiley & Sons Ltd.)

- Abstract
Importance: Biological data are lacking with respect to risk of vertical transmission and mechanisms of fetoplacental protection in maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection., Objective: To quantify SARS-CoV-2 viral load in maternal and neonatal biofluids, transplacental passage of anti-SARS-CoV-2 antibody, and incidence of fetoplacental infection., Design, Setting, and Participants: This cohort study was conducted among pregnant women presenting for care at 3 tertiary care centers in Boston, Massachusetts. Women with reverse transcription-polymerase chain reaction (RT-PCR) results positive for SARS-CoV-2 were recruited from April 2 to June 13, 2020, and follow-up occurred through July 10, 2020. Contemporaneous participants without SARS-CoV-2 infection were enrolled as a convenience sample from pregnant women with RT-PCR results negative for SARS-CoV-2., Exposures: SARS-CoV-2 infection in pregnancy, defined by nasopharyngeal swab RT-PCR., Main Outcomes and Measures: The main outcomes were SARS-CoV-2 viral load in maternal plasma or respiratory fluids and umbilical cord plasma, quantification of anti-SARS-CoV-2 antibodies in maternal and cord plasma, and presence of SARS-CoV-2 RNA in the placenta., Results: Among 127 pregnant women enrolled, 64 with RT-PCR results positive for SARS-CoV-2 (mean [SD] age, 31.6 [5.6] years) and 63 with RT-PCR results negative for SARS-CoV-2 (mean [SD] age, 33.9 [5.4] years) provided samples for analysis. Of women with SARS-CoV-2 infection, 23 (36%) were asymptomatic, 22 (34%) had mild disease, 7 (11%) had moderate disease, 10 (16%) had severe disease, and 2 (3%) had critical disease. In viral load analyses among 107 women, there was no detectable viremia in maternal or cord blood and no evidence of vertical transmission. Among 77 neonates tested in whom SARS-CoV-2 antibodies were quantified in cord blood, 1 had detectable immunoglobuilin M to nucleocapsid. Among 88 placentas tested, SARS-CoV-2 RNA was not detected in any. In antibody analyses among 37 women with SARS-CoV-2 infection, anti-receptor binding domain immunoglobin G was detected in 24 women (65%) and anti-nucleocapsid was detected in 26 women (70%). Mother-to-neonate transfer of anti-SARS-CoV-2 antibodies was significantly lower than transfer of anti-influenza hemagglutinin A antibodies (mean [SD] cord-to-maternal ratio: anti-receptor binding domain immunoglobin G, 0.72 [0.57]; anti-nucleocapsid, 0.74 [0.44]; anti-influenza, 1.44 [0.80]; P < .001). Nonoverlapping placental expression of SARS-CoV-2 receptors angiotensin-converting enzyme 2 and transmembrane serine protease 2 was noted., Conclusions and Relevance: In this cohort study, there was no evidence of placental infection or definitive vertical transmission of SARS-CoV-2. Transplacental transfer of anti-SARS-CoV-2 antibodies was inefficient. Lack of viremia and reduced coexpression and colocalization of placental angiotensin-converting enzyme 2 and transmembrane serine protease 2 may serve as protective mechanisms against vertical transmission.

- Abstract
Myocardial infarction (MI) not only defines acute MI with obstructed coronary arteries (T1MI) but also myocardial necrosis caused by myocardial oxygen supply/demand mismatch as type 2 MI (T2MI); only T1MI patients benefit from an early invasive management. Myeloid-related protein(MRP)-8/14 is a biomarker described in various inflammatory diseases and in MI patients. Here we evaluate the potential of MRP-8/14 and high-sensitivity troponin I (hs-cTnI) to differentiate T2MI from T1MI. Patients with final diagnosis NSTEMI (n = 254; 33.1% female) enrolled in a prospective biomarker registry between 08/2011 and 10/2016 were analysed. Median baseline MRP-8/14 levels were higher in T2MI (n = 55; 3.37(1.88-6.48)μg/mL) than in T1MI (n = 199; 2.4 [1.4-3.79]μg/mL) (p = .013) patients, in contrast to hs-cTnI (T2MI:52[11.65-321.4]ng/L vs. T1MI:436.5 [61.25-1973.8]ng/L; p < .001). To detect the strength of this association odds ratios(OR) were calculated with MRP-8/14 yielding 2.13(1.16-3.92; p = .015) to predict T2MI and 0.47(0.26-0.87; p = .015) for T1MI. As expected, hs-cTnI yielded an OR of to predict T2MI 0.34(0.17-0.65; p = .001) and 2.98(1.53-5.81; p = .001) for T1MI. Both markers show comparable and independent results if adjust to hs-cTnI/MRP-8/14, TIMI risk score and CRP. T2MI is associated with higher MRP-8/14 and lower hs-cTnI concentrations than T1MI. Our data suggest that MRP-8/14 as a marker of inflammation might provide usable discriminatory information complementing hs-cTnI in a diagnostic procedure evaluating the type of MI directly upon hospital admission., Competing Interests: Declaration of competing interest C.W.H. received lecture or consulting honoraria from Astra Zeneca, Bayer, Boehringer Ingelheim, GSK, Daiichi-Sankyo and Pfizer-Bristol-Myers Squibb; speaker fees and honoraria from Abbott Vascular.

- Abstract
Background: The aims of this study were to identify factors influencing participation in global health electives during residency and to understand the career impact of global health electives on alumni of an Obstetrics and Gynecology (OB/GYN) residency program., Methods: This was a cross-sectional, web-based survey of alumni of a residency program in the United States., Results: The response rate was 49%. Out of 73 respondents, 29 (39.7%) had completed a global health elective. Availability of funds and flexibility of elective time were the main enabling factors for participating in global health electives. Most participants of global health electives in residency reported a positive impact on their competence in domestic and global women's health and on their career choices. Completing a global health elective in residency was associated with career work in global health and/or local health disparities (OR 4.62 (95% CI: 1.20-17.87))., Conclusion: Global health electives are important in the career development of residents. To foster OB/GYNs that continue global health and health disparities work, OB/GYN programs should give trainees the opportunity to participate in funded global health electives.

- Abstract
Objective: To examine the microbiology and associated antibiotic resistance patterns among febrile peripartum women with positive blood cultures., Methods: We conducted a retrospective cohort study in which we reviewed all bacteremia cases between 2009 and 2016 that occurred between 7 days before and 30 days after delivery. Institutional guidelines include obtaining blood cultures and promptly initiating intravenous antibiotics for all obstetric patients with fever of 100.4°F or higher. We describe antibiotic resistance patterns for the most frequently isolated organisms and perform univariate analyses regarding maternal and neonatal outcomes based on type of bacteremia., Results: Among 56,835 deliveries, 3,797 (6.7%) obstetric patients had blood cultures drawn and 120 (3.2%) had documented bacteremia. The most commonly cultured organisms were Escherichia coli (17.5%, n=21), Bacteroides species (10.8%, n=13), Enterococcus species (10.8%, n=13), group B streptococci (10.8%, n=13), and group A streptococci (5.0%, n=6). E coli had high rates of resistance to ampicillin (n=17, 81.0%) and extended spectrum beta lactams (n=10, 47.6%). Gram-positive bacteremia was noted in 65/120 patients (54.2%), gram-negative bacteremia in 39/120 (32.5%), and anaerobic bacteremia in 16/120 (13.3%) (P=.02). Neonatal bacteremia was identified in 8/120 cases (6.7%), of which 7/8 (87.5%) were attributable to gram-negative bacteria and 1/8 (12.5%) were attributable to gram-positive bacteremia (P=.004). There were no differences in neonatal death or maternal intensive care unit admission., Conclusion: Peripartum bacteremia is uncommon, with the most frequently isolated organism being E coli. The evolution of antibiotic resistance patterns in E coli at our institution may be of clinical significance in determining antibiotic choice for peripartum fever.

- Abstract
Objective: To investigate the test characteristics of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) criteria for intrauterine inflammation or infection or both (triple I) and rates of adverse outcomes in a cohort of febrile intrapartum women., Methods: This retrospective cohort study included women at 24 weeks of gestation or greater from June 2015 to September 2017 at a single tertiary hospital with a temperature 100.4°F or greater (38.0°C) during labor or within 1 hour postpartum, all of whom had blood culture data. Women with a fetal demise, expectantly managed preterm prelabor rupture of membranes, or nonobstetric infections were excluded. Documented fever was defined as a single temperature 102.2°F or greater (39.0°C) or a temperature 100.4°F or greater (38.0°C) but less than 102.2°F (39.0°C) on two measurements 45 minutes apart. We defined two analysis groups: 1) suspected triple I, defined as women with documented fever with clinical signs of infection; and 2) isolated maternal fever, defined as women with at least one temperature 100.4°F or greater (38.0°C) who did not meet criteria for suspected triple I. We assessed test characteristics of suspected triple I to predict 1) confirmed triple I, defined as suspected triple I with placental pathology diagnostic of infection; and 2) adverse clinical infectious outcome, defined as a composite of maternal and neonatal adverse infectious outcomes. We also calculated the incidence of adverse clinical infectious outcomes for both groups., Results: Three hundred thirty-nine women were analyzed: 212 with suspected triple I and 127 with isolated maternal fever. Baseline demographic and obstetric characteristics were similar between groups. The incidence of adverse clinical infectious outcomes was 11.8% among women with suspected triple I and 9.5% among women with isolated maternal fever (P=.50). The sensitivity and specificity of suspected triple I for confirmed triple I were 71.4% (95% CI 61.4-80.1%) and 40.5% (95% CI 33.6-47.8%), respectively, and for an adverse clinical infectious outcome were 67.6% (95% CI 50.2-82.0%) and 38.1% (95% CI 32.6-43.8%), respectively., Conclusion: Applying the NICHD criteria to guide clinical diagnosis and management of intrauterine infection or inflammation may overlook an important proportion of laboring febrile women at risk for adverse infectious outcomes.

- Abstract
Aim: To characterize the understanding of hepatitis B virus (HBV) and determine if outreach improves HBV understanding among Greater Boston Area immigrants., Methods: Six outreach sessions were held in various community venues in the Greater Boston Area. Verbal consent was obtained from participants prior to starting each session. Each session included a pre-session questionnaire, followed by a teaching session, and then a post-session questionnaire. In person interpreters were present for translation during the teaching session and assistance for questionnaire completion when needed. The questions were developed based on the HBV clinical experience of physicians who serve largely immigrant populations. Questionnaires included Likert-type scale, open-ended, and true-false questions. All results were anonymous., Results: One hundred and one people participated in this study. Participants were 30% male with ages ranging from 19 to 87 years. The study population included immigrants from 21 countries, as well as seven United States-born participants. The greatest numbers of participants were from Somalia (44%), Morocco (10%), and Cameroon (8%). Pre session questionnaires revealed that 42% of participants were unaware that HBV can cause cancer, and 50% were unaware that therapies for HBV exist. Our brief teaching intervention led to improved scores on post session questionnaires. For example, at baseline, 58% of participants responded correctly to the question "HBV infection can cause scarring of the liver and liver cancer", whereas 79% of participants responded correctly after the teaching session ( P = 0.01). Furthermore, the mean of total correct answers in the true or false portion of the questionnaire increased from 5.5 to 7.6 ( P < 0.001)., Conclusion: A teaching session targeting Boston Immigrants at-risk for HBV helped improve scores on HBV knowledge questionnaires. Outreach may empower at-risk patients to pro-actively seek HBV care., Competing Interests: Conflict-of-interest statement: Dahlene Fusco has received support towards this study from Gilead.

- Abstract
Importance: Mosquitoes are the most common disease vectors worldwide. A combination of factors, including changes in public health policy, climate change, and global travel, has led to the resurgence and spread of these diseases in our modern world. Pregnant women are vulnerable to a number of these illnesses, and obstetricians are likely to encounter pregnant travelers who have been exposed., Objective: This review was conducted to summarize knowledge of mosquito-borne diseases and their relevance in pregnancy. This will allow obstetricians to provide proper advice regarding travel and prepare providers to recognize manifestations of these illnesses in the pregnant woman., Evidence Acquisition: A review of the current literature was performed to summarize the various manifestations of mosquito-borne illnesses in pregnant women and discuss obstetric outcomes and management of disease in pregnancy., Results: Mosquito-borne illnesses usually manifest after a period of incubation lasting from days to weeks. Symptoms usually include a febrile illness but may be nonspecific and may masquerade as pregnancy-specific illnesses such as preeclampsia or HELLP (hemolysis, elevated liver enzyme levels, and low platelet levels); a large number of patients remain asymptomatic. Pregnancy-related outcomes include spontaneous abortion, intrauterine fetal demise, intrauterine transmission to the fetus, and congenital anomalies. Management during pregnancy is mainly supportive. Precautions against disease include protective clothing and insect repellents. Vaccines are either available or in development., Conclusions and Relevance: Mosquito-borne disease should be considered in pregnant women who present with a febrile illness and a relevant exposure history. Prompt recognition can allow supportive treatment to the mother and fetal resuscitation and surveillance.

- Abstract
Unlabelled: Background Currently there are no guidelines regarding optimal screening for latent tuberculosis infection during pregnancy. Objective This study measures completion rates and the concordance between the TSPOT.TB, a commercially available interferon gamma release assay (IGRA), and the traditional tuberculin skin test (TST) in a predominantly urban minority obstetrics practice. Design This is an observational cohort study of 141 pregnant women enrolled from an obstetrics practice with a large immigrant population. Women with a history of a positive TST result were excluded. Demographic and clinical risk factors for tuberculosis were assessed. Enrolled women underwent a T-SPOT.TB test and placement of TST, and returned in 48-72 h for TST interpretation. We calculated the completion rate and frequency of a positive result for each test, as well as the concordance between the T-SPOT.TB and TST. Results Among the 141 women enrolled, 75 % were either Latina or African-American, 44 % were born in a country with a high TB prevalence, and 52 % had received the Bacillus Calmette-Guerin vaccine. Seven women (5 %) had a positive screening test, a total of 3 positive T-SPOT.TB results and 6 positive TST results, and all were from countries with a high TB prevalence. The concordance of the two tests was 96.3 %. The completion rate for the T-SPOT.TB was 98 %, while the completion rate for the TST was 63 %., Conclusion: The IGRA test had a markedly higher completion rate in addition to maintaining high concordance with the two-step TST in this population of pregnant women with a high prevalence of prior TB exposure. Targeted screening of women from countries with a high prevalence of tuberculosis may be warranted during prenatal care.

- Abstract
Mycoplasma genitalium is a facultative anaerobic organism and a recognized cause of nongonococcal urethritis in men. In women, M. genitalium has been associated with cervicitis, endometritis, pelvic inflammatory disease (PID), infertility, susceptibility to human immunodeficiency virus (HIV), and adverse birth outcomes, indicating a consistent relationship with female genital tract pathology. The global prevalence of M. genitalium among symptomatic and asymptomatic sexually active women ranges between 1 and 6.4%. M. genitalium may play a role in pathogenesis as an independent sexually transmitted pathogen or by facilitating coinfection with another pathogen. The long-term reproductive consequences of M. genitalium infection in asymptomatic individuals need to be investigated further. Though screening for this pathogen is not currently recommended, it should be considered in high-risk populations. Recent guidelines from the Centers for Disease Control regarding first-line treatment for PID do not cover M. genitalium but recommend considering treatment in patients without improvement on standard PID regimens. Prospective studies on the prevalence, pathophysiology, and long-term reproductive consequences of M. genitalium infection in the general population are needed to determine if screening protocols are necessary. New treatment regimens need to be investigated due to increasing drug resistance.

- Abstract
Age and growth of Rhizoprionodon acutus were estimated from vertebrae age bands. From December 2009 to November 2010, 423 R. acutus between 37 and 112 cm total length (LT ) were sampled along the Senegalese coast. Marginal increment ratio was used to check annual band deposition. Three growth models were adjusted to the length at age and compared using Akaike's information criterion. The Gompertz growth model with estimated size at birth appeared to be the best and resulted in growth parameters of L∞ = 139.55 (LT ) and K = 0.17 year(-1) for females and L∞ = 126.52 (LT ) and K = 0.18 year(-1) for males. The largest female and male examined were 8 and 9 years old, but the majority was between 1 and 3 years old. Ages at maturity estimated were 5.8 and 4.8 years for females and males, respectively. These results suggest that R. acutus is a slow-growing species, which render the species particularly vulnerable to heavy fishery exploitation. The growth parameters estimated in this study are crucial for stock assessments and for demographic analyses to evaluate the sustainability of commercial harvests., (© 2015 The Fisheries Society of the British Isles.)

- Abstract
Background: Diarrhoea is the second leading cause of child mortality worldwide. Low- and middle-income countries are particularly burdened with this both preventable and treatable condition. Targeted interventions include the provision of safe water, the use of sanitation facilities and hygiene education, but are implemented with varying local success., Objective: To determine the prevalence of and factors associated with diarrhoea in children under five years of age in rural Burundi., Design: A cross-sectional survey was conducted among 551 rural households in northwestern Burundi. Areas of inquiry included 1) socio-demographic information, 2) diarrhoea period prevalence and treatment, 3) behaviour and knowledge, 4) socio-economic indicators, 5) access to water and water chain as well as 6) sanitation and personal/children's hygiene., Results: A total of 903 children were enrolled. The overall diarrhoea prevalence was 32.6%. Forty-six per cent (n=255) of households collected drinking water from improved water sources and only 3% (n=17) had access to improved sanitation. We found a lower prevalence of diarrhoea in children whose primary caretakers received hygiene education (17.9%), boiled water prior to its utilisation (19.4%) and were aged 40 or older (17.9%). Diarrhoea was associated with factors such as the mother's age being less than 25 and the conviction that diarrhoea could not be prevented. No gender differences were detected regarding diarrhoea prevalence or the caretaker's decision to treat., Conclusions: Diarrhoea prevalence can be reduced through hygiene education and point-of use household water treatment such as boiling. In order to maximise the impact on children's health in the given rural setting, future interventions must assure systematic and regular hygiene education at the household and community level.

- Abstract
Female Genital Cutting (FGC) refers to the practice of surgically removing all or part of the female external genitalia for non-medical purposes. It is a common practice in many countries in Africa, the Middle East, and to a lesser extent, Asia. Over 130 million women worldwide have undergone this procedure, and over 2 million women and girls are subject to it every year. Various complications have been described, including infection, hemorrhage, genitourinary and obstetric complications, as well as psychological sequelae. Since the beginning of the HIV epidemic, a few reports have also described a potentially elevated risk of HIV transmission among women with FGC. In this report, we aim to review the evidence and identify unanswered questions and research gaps regarding a potential association between FGC and HIV transmission., (© 2012 John Wiley & Sons A/S.)

Molina RL, Diouf K, and Nour NM
- Abstract
Tuberculosis (TB) infection poses substantial challenges for obstetricians and gynecologists globally, as gynecologic involvement may cause infertility, irregular bleeding, and pelvic pain. If TB-infected women are able to conceive, obstetric complications include intrauterine growth restriction and, more rarely, congenital transmission. Appropriate screening for high-risk populations is crucial for diagnosis and treatment of latent and active TB infection, which may prevent reproductive sequelae for individual patients and, eventually, contribute to complete eradication of the disease.

- Abstract
The study highlights the potential of the black-chinned tilapia to be used as a sentinel to assess environmental contaminants based on the use of a set of biomarkers. The usefulness of fish species as sentinels for assessing aquatic environment contamination was tested using a set of biomarkers in Senegalese environments characterized by multi-pollution sources. The black-chinned tilapia (Sarotherodon melanotheron) was selected as a sentinel because of its abundance, wide distribution in all coastal aquatic ecosystems and physiological properties. The potential influence of confounding factors such as salinity on biomarker in the tilapia has been examined. Individuals were sampled during two seasons (dry and wet) in eight sites characterized by various degrees of anthropogenic contamination and different salinities (from 0 to 102 psu). Biomarkers-including growth rate (GR), condition factor (CF), biotransformation enzymes such as 7-ethoxyresorufin-O-deethylase (EROD) and glutathione-S-transferase (GST), lipid peroxidation (TBARS) and acetylcholinesterase (AChE)-were measured. Chemical contaminant [polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs)] levels showed different sources of contamination with relatively high concentrations of PAHs in the Hann Bay and Foundiougne locations. The most sensitive biomarker present in different sites according to the principal component analysis is EROD. Few variations of the AChE activity and TBARS levels were found. No clear relationship was found between biomarker responses and salinity, but GR and CF were lower in hypersaline conditions. Tilapia is responsive to environmental contaminants such as PAHs, OCPs and PCBs. The S. melanotheron multiparametric approach showed a better discrimination of sites.

- Abstract
Tetanus is an acute disease manifested by motor system and autonomic nervous system instability. Maternal and neonatal tetanus occur where deliveries are performed under unsanitary circumstances and unhygienic umbilical cord practices are prevalent. Neonatal tetanus is almost always fatal in the absence of medical care. These deaths can be prevented with changes in traditional obstetrical practices and maternal immunization. This situation led to the development of the Maternal and Neonatal Elimination Initiative by the World Health Organization. Using a three-pronged approach, tetanus can be eliminated via promotion of hygienic practices during delivery, maternal and childhood immunization, and close surveillance.

40. New Success With Microbicides and Pre-Exposure Prophylaxis for Human Immunodeficiency Virus (HIV): Is Female-Controlled Prevention the Answer to the HIV Epidemic?

- Abstract
Women who cannot negotiate condom use with their partners, often due to socioeconomic factors and sexual abuse, have no means of preventing themselves from acquiring the human immunodeficiency virus (HIV). There is a need to develop HIV-preventive methods initiated and controlled by women. Microbicides and other pre-exposure prophylaxis may help fill that need. Although two decades of research on broad-spectrum microbicides have generally been disappointing, recent trials with HIV-specific agents have yielded promising initial results. A new era of clinical research involves novel biochemical prevention methods, including HIV-specific vaginal microbicides and oral antiretroviral chemoprophylaxis drugs (pre-exposure prophylaxis; PrEP) that may help provide more control for women.

- Abstract
Objective. Cervical human papillomavirus (HPV) infection has been associated with human immunodeficiency virus (HIV) acquisition in populations with a high prevalence of both infections. Procedures performed in the management of cervical dysplasia may facilitate HIV entry via mechanical injury. We sought to investigate the association between cervical procedures and incident HIV. Methods. Data on cervical cancer screening and procedures were collected in a cohort study evaluating the diaphragm for HIV prevention in 2040 women. In this secondary analysis, we investigated the association between cervical procedures and HIV acquisition. Results. Out of 2027 HIV-negative women at baseline, 199 underwent cervical procedures. Cumulative risk of HIV was 4.3% over 21 months of median followup (n = 88). Compared with women without cervical procedures, we observed no difference in HIV incidence after a cervical biopsy (RR 0.92, 95% CI 0.39-2.16), endocervical curettage (RR 0.29, 95% CI 0.07-1.22), or loop electrosurgical excision procedure (RR 1.00, 95% CI 0.30-3.30). Conclusions. In this cohort, cervical procedures were not associated with HIV incidence. This lack of association could be due to the small number of events.

- Abstract
Objectives: Human immunodeficiency virus type 2 (HIV-2) progression to disease is significantly slower than that of human immunodeficiency virus type 1 (HIV-1). Genetic determinants for susceptibility to disease progression were hypothesized to play a more significant role in this infection compared with HIV-1. We sought to identify common human lymphocyte antigen (HLA) alleles in the Senegalese population and to compare HLA profiles between HIV-2-infected individuals with low and high risk for disease progression., Study Design/methods: We conducted a case-control study investigating possible associations between MHC class I genes and the risk of disease progression in HIV-2-infected individuals. The MHC class I genotype was molecularly defined using polymerase chain reaction with sequence specific primers (PCR-SSP) in 62 female sex workers from the Dakar, Senegal cohort. Lack of antibodies to the HIV-2 antigen p26 has been previously shown to predict disease progression and was used in this study as a surrogate marker. Twenty-one cases were identified lacking antibodies to p26, therefore at a higher risk of disease progression, and were compared with 41 p26 antibody-positive, randomly selected controls., Results: Statistical analysis showed that HLA B35 was significantly associated with lack of p26 antibodies, and higher risk of disease progression ( < 0.05). The same association was found for the self-defined class I haplotypes B35-Cw4 and A23-Cw 7 ( < 0.05). The HLA B 53 allele was associated with slower disease progression; however, this association was not statistically significant. We observed a trend whereby heterozygotes were at lower risk for HIV-2 disease progression, as previously reported in HIV-1 disease., Conclusions: In this West African population, a distinct profile of HLA class I alleles was observed, and many of these appear to influence disease progression in HIV-2 infection.
